AIR CORE INDUCTORS
High-Reliability AirCoreInductorsMS475RAT
■ High Q over a wide range of frequencies
■ High temperature materials allow operation in ambient
temperatures up to 155°C.
■ Tin-lead (Sn-Pb) terminations ensure the best possible
board adhesion

1. When ordering, specify tolerance and testing codes:
MS475RATR15GSZ
Tolerance: G = 2%  J = 5%
Testing: Z = COTS
H = Screening per Coilcraft CP-SA-10001
N = Screening per Coilcraft CP-SA-10003
2. Inductance measured at 150 MHz on an Agilent/HP 4286A or equiva-
lent with a Coilcraft SMD-A test fixture and correlation.
3. Q measured at 150 MHz on an Agilent/HP 4291A or equivalent with a
16193A test fixture or equivalent.
4. SRF measured on an Agilent/HP 8753ES or equivalent with a Coilcraft
CCF1268 test fixture.
5. DCR measured on a Keithley 580 Micro-Ohmmeter or equivalent.
6. Electrical specifications at 25°C.
